Description

  The present invention relates to a slide mechanism that connects two housings so as to be relatively movable, a portable communication terminal including the same, and a slide movement method.

  2. Description of the Related Art Conventionally, portable communication terminals that transmit and receive various data by wireless transmission and reception have been made multifunctional. The portable communication terminal can receive and receive videophone calls and television broadcasts, browse websites, etc. in addition to sending and receiving calls and sending and receiving emails. Such a multifunctional portable communication terminal preferably includes a display screen unit having a larger screen in order to display the received image data and character data satisfactorily.

However, when the display screen unit and the operation unit are enlarged, the entire apparatus is enlarged on the other hand, which is not preferable from the viewpoint of maintaining good portability as a portable communication terminal.
For this reason, slide-type and rotary-type portable communication terminals have been proposed so as to minimize the size of the entire apparatus while increasing the size of the display screen unit and operation unit. In a slide-type portable communication terminal, an operation unit and a display screen unit are separately provided on a pair of casings, and these casings are slidably attached to each other with a slide mechanism. In a rotary type portable communication terminal, each casing is attached so as to be rotatable with respect to each other.

Some of the multifunctional portable communication terminals as described above have a function that originally assumes a horizontally long screen such as browsing a television broadcast or referring to a website. In such a portable communication terminal, it is strongly required that the display screen unit is a horizontally long screen as seen from the user, such as a television receiver or a personal computer. In such a case, it is most convenient for the user that the operation unit is positioned below the center of the display screen as viewed from the user.
Therefore, conventionally, the display screen unit is a horizontally long screen when viewed from the user, and the operation unit is operated in a state where the operation unit is positioned below the center of the display screen unit when viewed from the user. There has been proposed a portable communication terminal in which the first and second casing parts are slid relative to each other after the second casing part is rotated by 90 ° from the initial state (see, for example, Patent Document 1).

  As described above, in the portable communication terminal in which the display screen unit is a horizontally long screen when viewed from the user and the operation unit is positioned below the center of the display screen unit, specifically, the convenience of the terminal operation Therefore, it is required that the following two functions can be selected. The first function is a conventional function that operates the terminal from the closed state in the initial state to the vertically open state in which the display screen portion in the normal use state is viewed from the user. The second function is from a closed state to an open state in which the display screen unit is a horizontally long screen when viewed from the user and the operation unit is positioned below the center of the display screen unit as viewed from the user. Is a function to operate the terminal. With these functions, the time for shifting to the open state suitable for the function desired by the user is shortened.

  However, according to the slide mechanism described above, the pair of casing portions can be relatively moved from the basic position to a specific one usage state, but the casing portions are in different usage states. I couldn't. That is, when such a slide mechanism is applied to, for example, a portable communication terminal as described above, the other casing having the display screen unit is placed in the same orientation with respect to the one casing having the operation unit. Depending on the mechanism, it is necessary to select either the relative movement to use or the 90 ° relative rotation to use as a horizontal orientation. For this reason, in recent years, it has not been possible to obtain operability suitable for each function despite the demand for multifunctional portable communication terminals. Further, in the above slide mechanism, from the state in which one housing and the other housing are overlapped with each other to change to a substantially T-shaped state as a specific use state, a linear movement is performed after slide rotation. There was a need to do. For this reason, it is necessary to perform a plurality of operations when switching the usage state.

  The present invention has been made in view of the above-described circumstances. The present invention relates to a slide mechanism, a portable communication terminal, and a slide that are capable of relatively sliding the casing portions to positions that are in different usage states from the positions that are the basic positions by only a single operation. Provide a moving method.

In order to solve the above problems, the present invention proposes the following means.
The slide mechanism of the present invention is provided between a first housing part and a second housing part arranged so as to face each other, and A second housing part is movable relative to the first surface of the first housing part from a basic position, the first slit provided in the first housing part, and the first housing A second slit provided in parallel to the first slit, a third slit provided in the second casing, and the third slit in the second casing. A fourth slit provided in parallel with the slit, and the first slit and the third slit inserted into the first slit and the third slit to connect the first slit to the first slit. And a first support shaft that is movable along the third slit, and the second slit and the fourth slit. Has been connected to the housing part and the first housing portion, and a second shaft which is movable along said second slit and the fourth slit.

  In the slide movement method of the present invention, the second casing unit arranged so that one surface faces each other with respect to the first casing unit is moved from the basic position to the first casing unit. Relative movement on one surface, enabling relative movement in a predetermined linear movement direction from the basic position, and further, at the basic position, the second casing portion with respect to the first casing portion. The first casing portion is rotatable about the first support shaft, which is a predetermined center of rotation on the one surface, in a direction of rotation relative to one direction, and is different from the first support shaft. The second support shaft can be rotated relatively in the other direction side opposite to the one direction side in the rotation direction.

The slide mechanism of the present invention includes a first slit, a second slit, a third slit and a fourth slit, and a first support shaft and a second support shaft inserted into these. For this reason, according to the slide mechanism of the present invention, the use positions moved relative to each other along the moving direction from the positions where the casings are set as the basic positions are different from the use positions that are relatively rotated. Each position can be relatively slid by only a single operation.
Further, according to the slide movement method of the present invention, the use position moved relatively along the movement direction from the position where the casings are set as the basic position, and the use position moved relative to each other are used in different positions. Can be relatively slid by only a single operation.

As an example, each part constituting the slide mechanism 20 is partially or entirely formed of a steel material or a resin material, and is molded into each shape by press molding or injection molding.

The first spring member 27 and the second spring member 28 function as a holding portion that holds the positional relationship between the first slit member 21 and the second slit member 22. Further, the first spring member 27 and the second spring member 28 function as an auxiliary portion that assists the movement operation and the rotation operation when the first slit member 21 and the second slit member 22 are slid. To do. As the first spring member 27, for example, a torsion coil spring is used. The first spring member 27 has one end 27 a fixed to the first slit member 21 and the other end 27 b fixed to the first support shaft 23. More specifically, the first slit member 21 has a substantially cylindrical shape at a position approximately spaced from the first slit 31 in a direction orthogonal to the moving direction S at the approximate center of the moving direction S of the first slit 31. A first supporting convex portion 21b is provided.

The first spring member 27 is attached to the first support convex portion 21b and the second support convex portion 23f so as to narrow the distance between the one end 27a and the other end 27b. Thus, the first support convex portion 21b and the second support convex portion 23f are urged by the first spring member 27 so as to always increase the distance from each other.
For this reason, when the first support shaft 23 is located on the one slit end 31 a side from the center position along the moving direction S of the first slit 31, the first support shaft 23 is along the first slit 31. It is urged toward one slit end 31a. On the other hand, when the 1st spindle 23 is located in the other slit end 31b side, it is urged | biased toward the other slit end 31b side. That is, the first support shaft 23 is urged toward the slit ends 31 a and 31 b by the first spring member 27 according to the position in the first slit 31.

As the second spring member 28, for example, a torsion coil spring is used. The second spring member 28 is fixed to the first engagement member 25 having one end 28 a fixed to the second slit member 22 and the other end 28 b fixed to the first support shaft 23. More specifically, the second slit member 22 has a substantially cylindrical shape at a position spaced apart from the third slit 33 in a direction orthogonal to the movement direction S in the approximate center of the movement direction S of the third slit 33. A third supporting convex portion 22b is provided. One end 28a of the second spring member 28 is wound around the third support convex portion 22b and attached rotatably around the third support convex portion 22b.

The other end 28b of the second spring member 28 is wound around the fourth support convex portion 25b, and is attached rotatably around the fourth support convex portion 25b. The second spring member 28 is attached to the third support convex portion 22b and the fourth support convex portion 25b so as to narrow the distance between the one end 28a and the other end 28b. Thus, the third support convex portion 22b and the fourth support convex portion 25b are urged by the second spring member 28 so as to always increase the distance from each other.
For this reason, when the first support shaft 23 is located on the one slit end 33 a side of the center position along the moving direction S of the third slit 33, the first support shaft 23 is along the third slit 33. It is biased toward the one slit end 33a. On the other hand, when the first support shaft 23 is positioned on the other slit end 33b side on the opposite side, it is biased toward the other slit end 33b side. That is, the second support shaft 24 is urged toward the slit ends 33 a and 33 b by the second spring member 28 according to the position in the third slit 33.

  Next, the operation of the portable terminal 1 and the slide mechanism 20 of this embodiment will be described with reference to FIGS. FIGS. 10 to 21 are schematic diagrams showing the positional relationship in each state for each configuration of the first casing unit 2, the second casing unit 3, and the slide mechanism 20, and are minimal for explanation. Only the configuration is displayed.

  As shown in FIG. 1, in the state of the basic position P, the entire portable terminal 1 is compact, and the display screen unit 11 provided on the second main surface 8 of the second housing unit 3 and The second operation unit 9 is exposed to the outside. For this reason, the operator can check the information on the display screen unit 11 and can perform a minimum basic operation using the second operation unit 9. In this state, as shown in FIGS. 10 and 11, in the slide mechanism 20, the first support shaft 23 has one slit end 31 a of the first slit 31 of the first slit member 21, and the second The slit member 22 is located at the other slit end 33 b of the third slit 33. The second support shaft 24 is connected to one slit end 32 a of the second slit 32 of the first slit member 21 and the other slit end 34 b of the fourth slit 34 of the second slit member 22. positioned. The first spring member 27 provided on the first slit member 21 side biases the first support shaft 23 toward the one slit end 31 a side of the first slit 31. The second spring member 28 provided on the second slit member 22 side biases the first support shaft 23 to the other slit end 33 b of the third slit 33. That is, the first casing 2 and the second casing 3 are held in a state where the first spring member 27 and the second spring member 28 are in the basic position P with the holding portions as the holding portions.

  The operator resists the urging by the first spring member 27 and the second spring member 28 toward the one side in the moving direction S of the second casing portion 3 with respect to the first casing portion 2. Give the operation force to move relative. By this operating force, the first support shaft 23 and the second support shaft 24 move in the first slit 31 and the third slit 33, and the second slit 32 and the fourth slit 34, respectively. It becomes possible to move in the direction S. Thereby, the 2nd housing | casing part 3 can move along the moving direction S used as the direction along mutual long sides 4a and 8a with respect to the 1st housing | casing part 2. FIG. As a result, in the slide mechanism 20, the first support shaft 23 and the second support shaft 24 move the first slit 31 and the third slit 33, and the second slit 32 and the fourth slit 34. Located in the center of direction S. That is, the 2nd housing | casing part 3 becomes the 3rd use position Q 'shown in FIG. Further, the first support shaft 23 and the second support shaft 24 pass through the center in the moving direction S of the first slit 31 and the third slit 33, and the second slit 32 and the fourth slit 34. Then, the direction of urging by the first spring member 27 and the second spring member 28 is reversed. For this reason, after this, the 1st spindle 23 and the 2nd spindle 24 are the other slit end 31b of the 1st slit 31 by the urging | biasing force of the 1st spring member 27 and the 2nd spring member 28. The first slit end 33 a of the third slit 33 and the other slit end 32 b of the second slit 32 and the one slit end 34 a of the fourth slit 34 are moved with assistance. That is, the first spring member 27 and the second spring member 28 function as auxiliary portions for assisting the operation. As a result, as shown in FIGS. 3, 12 and 13, until the first support shaft 23 comes into contact with the other slit end 31 b of the first slit 31 and one slit end 33 a of the third slit 33. Moving. Further, the second support shaft 24 moves until it comes into contact with the other slit end 32b of the second slit and one slit end 34b of the fourth slit 34. In this state, the urging force of the first spring member 27 and the second spring member 28 acts toward the other slit end 31 b of the first slit 31 and the other slit end 32 b of the second slit 32. To do. That is, the first spring member 27 and the second spring member 28 function as a holding portion. For this reason, the first support shaft 23 is pressed against the other slit end 31 b of the first slit 31 and one slit end 33 a of the third slit 33, and the engaged state is maintained. The second support shaft 24 is pressed against the other slit end 32 b of the second slit 32 and one slit end 34 a of the fourth slit 34, and the engaged state is maintained.

  Through the operation as described above, the first casing portion 2 and the second casing portion 3 are moved from the basic position P shown in FIG. 1 to the third use position Q ′ shown in FIG. It becomes one use position Q. Therefore, it becomes possible to use the portable terminal 1 in a state where the first casing 2 and the second casing 3 are arranged vertically and the first operation unit 41 is exposed. For this reason, the portable terminal 1 can be brought into an optimum state when using a function such as telephone communication.

  The operator is constant against the urging of the first spring member 27 and the second spring member 28 toward the other side of the moving direction S in the second casing 3 with respect to the first casing 2. Give the operation power. With this operating force, the first casing portion 2 and the second casing portion 3 shown in FIG. 3 change from the first use position Q to the third use position Q ′ shown in FIG. After that, it can be returned to the basic position P shown in FIG. Also in this case, when passing the position shown in FIG. 2, the direction of urging by the first spring member 27 and the second spring member 28 is reversed. After the position shown in FIG. 2, the first support shaft 23 and the second support shaft 24 are moved by the urging force of the first spring member 27 and the second spring member 28. The first slit end 31 a and the other slit end 33 b of the third slit 33 and the one slit end 32 a of the second slit 32 and the other slit end 34 b of the fourth slit 34 are assisted and moved. Thus, similarly, the first spring member 27 and the second spring member 28 function as an auxiliary portion for assisting the operation.

  The operator rotates the second casing 3 from the state where the first casing 2 and the second casing 3 are at the basic position P as shown in FIGS. An operating force is applied to the unidirectional side T1 to rotate the second casing 3 on the first main surface 4 with respect to the first casing 2. At this time, even if the first support shaft 23 is moved about the second support shaft 24 in the tangential direction of the rotational direction one direction T 1, the first support shaft 23 is one of the first slits 31. The slit end 31a and the other slit end 33b of the third slit 33 are engaged, and movement is restricted. On the other hand, when the second support shaft 24 is moved in the tangential direction on the one direction side T <b> 1 about the first support shaft 23, the second support shaft 24 is moved to one of the second slits 32. It moves relatively from the slit end 32a toward the other slit end 32b and from the other slit end 34b of the fourth slit 34 toward one slit end 34a. For this reason, when the operator gives an operating force to the second casing portion 3 in one direction T1 in the rotational direction, as shown in FIGS. 14 and 15, the second casing portion 3 The second support shaft 24 is slid and rotated with respect to the first housing portion 2 while the second support shaft 24 is slidably moved in the second slit 32 and the fourth slit 34 with the support shaft 23 as the center. Then, as shown in FIGS. 16 and 17, when the second support shaft 24 abuts against the other slit end 32b of the second slit 32 and one slit end 34a of the fourth slit 34, Engage and the rotation is restricted. In the present embodiment, the lengths of the second slit 32 and the fourth slit 34 are such that when the second support shaft 24 is rotated 90 degrees around the first support shaft 23, the second support shaft 24 is engaged with the slit ends 32b and 34a. Are set to match. As a result, the second casing 3 is rotated 90 degrees with respect to the first casing 2. The first casing 2 and the second casing 3 at the basic position P, the first support shaft 23, one slit end 31a of the first slit 31, and the other slit end of the third slit 33. As shown in FIGS. 5, 16, and 17, the first casing 2 and the second casing 3 have a substantially T-shape that is the second use position R, as shown in FIGS. 5, 16, and 17. be able to. For this reason, the 1st operation part 5 provided in the 1st housing | casing part 2 is exposed again. Further, the display screen unit 11 provided in the second housing unit 3 is oriented without changing the center position from the basic position P in the lateral direction (the direction along the short side 4b of the first housing unit 2). By changing 90 degrees, the second casing 3 can be made horizontally long with respect to the first casing 2. For this reason, while operating the first operation unit 5, the portable terminal 1 is brought into an optimal state when using functions as a television receiver or a personal computer, such as browsing a television broadcast or referring to a website. Can do.

  The first support shaft 23 has the rotation restricting portion 23c, so that the first slit 31 with respect to the first slit member 21 is kept constant with respect to the second slit member 22. Rotate within. For this reason, during the rotation operation, the relative orientation between the first support shaft 23 and the first slit member 21 changes, so that the urging force by the first spring member 27 also changes. A torque in a different direction acts between the two depending on the relative direction. That is, during the rotation operation, the second casing 3 is in a position where the second casing 3 is in the state shown in FIGS. Until the support shaft 24 reaches the center of the second slit 32 and the fourth slit 34, the first support shaft 24, the first slit member 21, and the like are urged by the biasing force of the first spring member 27. In the meantime, a torque acting to return to the basic position P as shown in FIGS. Therefore, due to this torque, the second support shaft 24 that moves in the second slit 32 and the fourth slit 34 has one slit end 32 a of the second slit 32 and the other of the fourth slit 34. A force to return to the slit end 34b is applied. On the other hand, when the second support shaft 24 passes through the center of the second slit 32 and the fourth slit 34, the first support shaft 24 and the first slit member are urged by the biasing force of the first spring member 27. Torque to rotate further in the same direction acts between the two. For this reason, a force acts on the second spindle 24 toward the other slit end 32 b of the second slit 32 and one slit end 34 a of the fourth slit 34 by this torque. Accordingly, after the state shown in FIGS. 4, 14, and 15, the second support shaft 24 causes the other slit end 32 b of the second slit 32 and the fourth to be urged by the biasing force of the first spring member 27. The slit 34 moves with assistance to one slit end 34a. That is, the first spring member 27 functions as an auxiliary portion for assisting the operation.

  In the state of the second use position R shown in FIGS. 5, 16, and 17, the biasing force by the first spring member 27 and the second spring member 28 causes the one slit end 31 a of the first slit 31 and the first It acts toward the other slit end 33 b of the three slits 33. That is, the first spring member 27 and the second spring member 28 function as a holding portion. Therefore, the first support shaft 23 is held in a state where it is pressed against one slit end 31 a of the first slit 31 and the other slit end 33 b of the third slit 33. The second support shaft 24 is held in a state of being pressed against the other slit end 32 b of the second slit 32 and one slit end 34 a of the fourth slit 34.

  The operator applies an operating force to the second casing 3 on the other direction side T2 on the opposite direction side to the one direction side T1 in the rotation direction. With this operating force, the first housing 2 is moved from the basic position P to the first housing 2 as shown in FIGS. 1, 10, and 11. On the other hand, the second casing 3 is rotated on the first main surface 4. At this time, even if an attempt is made to move the second support shaft 24 around the first support shaft 23 in the tangential direction of the other direction T2 in the rotational direction, the second support shaft 24 is one of the second slits 32. The slit end 32a and the other slit end 34b of the fourth slit 34 are engaged, and movement is restricted. On the other hand, when the first support shaft 23 is moved about the second support shaft 24 in the tangential direction on the other direction side T <b> 2 in the rotational direction, the first support shaft 23 is one of the first slits 31. It moves relatively from the slit end 31a toward the other slit end 31b and from the other slit end 33b of the third slit 33 toward one slit end 33a. For this reason, when the operator gives an operating force to the second casing 3 in the other direction T2 in the rotational direction, the second casing 3 is centered on the second support shaft 24, and the first The support shaft 23 is slid and rotated with respect to the first housing portion 2 while sliding within the first slit 31 and the third slit 33.

  As shown in FIGS. 20 and 21, when the first support shaft 23 abuts against the other slit end 31 b of the first slit 31 and one slit end 33 a of the third slit 33, these are engaged with each other. And its rotation is restricted. In the present embodiment, the lengths of the first slit 31 and the third slit 33 are such that when the first support shaft 23 is rotated 90 degrees around the second support shaft 24, the first support shaft 23 is engaged with the slit ends 31b and 33a. Are set to match. As a result, the second casing 3 is rotated 90 degrees with respect to the first casing 2. The first casing 2 and the second casing 3 at the basic position P, the second support shaft 24, one slit end 32a of the second slit 32, and the other slit end of the fourth slit 34. As shown in FIGS. 20 and 21, the first casing 2 and the second casing 3 can be substantially T-shaped, which is the second use position R, as shown in FIGS. . For this reason, the 1st operation part 5 provided in the 1st housing | casing part 2 is exposed again. Further, the display screen unit 11 provided in the second housing unit 3 is oriented without changing the center position from the basic position P in the lateral direction (the direction along the short side 4b of the first housing unit 2). By changing 90 degrees, the second casing 3 can be made horizontally long with respect to the first casing 2. For this reason, while operating the first operation unit 5, the portable terminal 1 is brought into an optimal state when using functions as a television receiver or a personal computer, such as browsing a television broadcast or referring to a website. Can do.

  During the rotation operation, the first spring member 27 and the second spring member 28 are attached until the first support shaft 23 reaches the center of the moving direction S of the first slit 31 and the third slit 33. Due to the force, a force is applied to the first support shaft 23 to return to the original position, that is, one slit end 31 a of the first slit 31 and the other slit end 33 b of the third slit 33. On the other hand, when the first support shaft 23 passes through the center of the first slit 31 and the third slit 33, the first support shaft is driven by the urging force of the first spring member 27 and the second spring member 28. The force acts on the other slit end 31 b of the first slit 31 and one slit end 33 a of the third slit 33. For this reason, after that, the first support shaft 23 has the other slit end 31 b of the first slit 31 and the third slit 33 by the urging force of the first spring member 27 and the second spring member 28. It moves with assistance to one slit end 33a. That is, the first spring member 27 and the second spring member 28 function as auxiliary portions for assisting the operation. In the state of the second use position R shown in FIGS. 20 and 21, the urging force by the first spring member 27 and the second spring member 28 is applied to the first support shaft 23 and the other of the first slits 31. It acts toward one slit end 33 a of the slit end 31 b and the third slit 33. That is, the first spring member 27 and the second spring member 28 function as a holding portion. For this reason, the first support shaft 23 is held in a state of being pressed against the other slit end 31 b of the first slit 31 and one slit end 33 a of the third slit 33. Further, the second spindle 24 is held in a state of being pressed against one slit end 32 a of the second slit 32 and the other slit end 34 b of the fourth slit 34.

  As described above, according to the portable terminal 1 of the present embodiment, the first casing 2 and the second casing 3 are moved from the basic position P shown in FIG. 1 to the first use shown in FIG. The position Q can be used in a state in which the first operation unit 5 is exposed while being arranged vertically long. Further, the first casing portion 2 and the second casing portion 3 shown in FIG. 3 can be returned to the basic position P shown in FIG. 1 from the first use position Q. Further, the first housing portion 2 and the second housing portion 3 are rotated by 90 degrees from the basic position P shown in FIG. As R, the 1st housing | casing part 2 and the 2nd housing | casing part 3 become a substantially T shape, the display screen part 11 is a horizontally long screen seeing from a user, and the 1st operation part 5 is from a user. It is possible to shift to an open state that is located below the central portion of the display screen unit 11 by a single operation. Furthermore, when the left and right orientations of FIG. 5 and the second casing portion 2 are different when rotated 90 ° in the other direction side T2 opposite to the one direction side T1 in the rotation direction, the same second use position R is used. The first casing 2 and the second casing 3 are substantially T-shaped, the display screen 11 is a horizontally long screen as viewed from the user, and the first operation unit 5 is viewed from the user. Thus, it is possible to shift to the open state located below the central portion of the display screen unit 11 by only a single operation. And since the slide mechanism 20 is provided with the 1st spring member 27 and the 2nd spring member 28, the state in each position can be hold | maintained as a holding | maintenance part. In addition, when operating force is given by the first spring member 27 and the second spring member 28 to move the second housing portion 3 relative to the first housing portion 2, an auxiliary force is used as an auxiliary portion. The operability can be improved by acting. Depending on the type and arrangement of the spring member, it may act only as a holding part or as an auxiliary part, but such a configuration may be adopted.

  The first slit 31, the second slit 32, the third slit 33, and the fourth slit 34 have the same slit length, the interval between the first slit 31 and the second slit 32, and the third slit 33. In the above description, the interval between the first slit 34 and the fourth slit 34 is set to be approximately equal to the slit length. However, the present invention is not limited to this. By changing the length of each slit and the position of the slit end, the position where the first support shaft 23 or the second support shaft 24 is locked and the movement is restricted at the slit end of each slit is different. As a result, the sliding amount from the basic position P in the moving direction S and the rotation angles to the rotation direction one direction side T1 and the other direction side T2 can be changed. Moreover, the moving direction S for moving from the basic position P to the first use position Q is in a direction along the long sides 4a and 8a of the first casing portion 2 and the second casing portion 3 at the basic position P. Although described above as being set, it is not limited to this. For example, the direction may be set along the short sides 4b and 8b, and the directions of the first slit 31, the second slit 32, the third slit 33, and the fourth slit 34 may be set accordingly. Furthermore, the moving direction S is not limited to a linear direction, and may be a specific line, for example, a direction along an arcuate curved shape.

  In the present embodiment, the basic position P has been described above as a position where the first casing portion 2 and the second casing portion 3 overlap each other without being displaced from each other. However, the basic position P is not limited to this. That is, for convenience of design, component arrangement, and the like, for example, the center lines in the long side direction and the short side direction of the first housing unit 2 and the second housing unit 3 do not have to be matched. Alternatively, at the basic position P, the first casing 2 and the second casing 3 have a predetermined angle such as 30 ° 45 ° 60 °, 120 ° 135 ° 150 °, or the like in the long side direction. In this state, the sliding movement in the predetermined movement direction S or the sliding rotation in the predetermined rotation direction may be adopted.

In the said embodiment, although the 1st spring member 27 and the 2nd spring member 28 were set as the structure by a torsion coil spring, it is not restricted to this, Various kinds of urging means are applicable.
In the above embodiment, only the first support shaft 23 is urged by the first spring member 27 and the second spring member 28. However, instead of the first support shaft 23, the second support shaft 24 may be similarly energized, or both the first support shaft 23 and the second support shaft 24 may be energized. .
In the above-described embodiment, the first spring member 27 and the second spring member 28 are used to maintain the positional relationship between the first casing portion 2 and the second casing portion 3. However, it is not limited to this. If the first support shaft 23 and the second support shaft 24 can be held at the slit ends of the first slit 31, the second slit 32, the third slit 33, and the fourth slit 34, an uneven surface It can also be replaced with a mechanism for holding by engagement or the like, for example, a click stop mechanism. These click stop mechanisms can also be provided between the first housing part 2 and the second housing part 3.

  Moreover, in the said embodiment, although the 1st housing | casing part 2 and the 2nd housing | casing part 3 assumed flat rectangular shape and the same shape, it is not restricted to this, Various shapes can be applied. It may be possible, and may have different shapes and sizes. In the embodiment described above, the slide mechanism 20 forms the first slit 31 and the second slit 32 in the first slit member 21, and the third slit 33 and the second slit 32 in the second slit member 22. Although the four slits 34 are formed, the present invention is not limited to this. Each of these slits can be formed by separate members, or these slits may be formed directly in the first casing portion 2 and the second casing portion 3. Furthermore, although the said embodiment demonstrated the portable terminal which has a 1st housing | casing part and a 2nd housing | casing part as an example which applies the slide mechanism 20, it is not restricted to this. As long as the portable terminals are slidably and pivotably connected to each other by the slide mechanism, the present invention can be applied to various portable terminals such as notebook computers, electronic dictionaries, and PDAs (personal data assistance). The embodiment can be effectively applied.

  In the above, the point which can be set from the basic position P to the 2nd use position R by slidingly rotating the 2nd housing | casing part 3 with respect to the 1st housing | casing part 2 was demonstrated. In addition to this, in the above configuration, the second use position R can be set from the first use position Q and the third use position Q ′. That is, for example, if the second housing part 3 is rotated from the first use position Q shown in FIGS. 12 and 13 to the one side T1 in the rotation direction, the first support is centered on the second support shaft 24. The shaft 23 rotates while relatively moving in the first slit 31 and the third slit 33, and can be set to the second use position R shown in FIGS. On the other hand, if the second casing 3 is rotated from the first use position Q shown in FIGS. 12 and 13 to the other direction T2 in the rotation direction, the second support shaft is centered on the first support shaft 23. 24 rotates while relatively moving in the second slit 32 and the fourth slit 34, and the left and right directions are different from those of the second casing portion 2 in the state shown in FIGS. The use position R can be set. The same applies to the third use position Q ′.

(Second Embodiment)
Next, a second embodiment of the present invention will be described. 22 to 49 show a second embodiment of the present invention. In this embodiment, members that are the same as those used in the above-described embodiment are assigned the same reference numerals, and descriptions thereof are omitted.

  As shown in FIG. 22, the portable terminal 40 of this embodiment is basically configured similarly to the first embodiment. The portable terminal 40 includes a first casing unit 2 and a second casing unit 3, and a slide mechanism 50. The 1st housing | casing part 2 and the 2nd housing | casing part 3 are arrange | positioned so that it may mutually oppose. The slide mechanism 50 is provided between the first housing part 2 and the second housing part 3, and slides and moves the second housing part 3 relative to the first housing part 2. Let As in the first embodiment, the portable terminal 40 slides in the moving direction S from the basic position P where the first main surface 4 and the slide surface 7 overlap each other without shifting as shown in FIG. It is possible to set the first use position Q by further sliding and making it possible to set the position to the third use position Q ′. Similarly to the first embodiment, the second casing 3 is slid and rotated relative to the first casing 2 relative to the one direction T1 in the rotation direction, whereby the long sides 4a of each other, It is possible to set the second use position R in which the direction along the line 8a is orthogonal and is substantially T-shaped as a whole. Furthermore, the second housing portion 3 is slid and rotated relative to the first housing portion 2 toward the other direction T2 in the rotational direction, so that the second use position R and the second operation portion 9 are positioned. It is possible to set the fourth use position U that is substantially T-shaped as a whole so as to be on the opposite side. In the present embodiment, two states that are rotated in different directions and are substantially T-shaped as a whole are distinguished from the second use position R and the fourth use position U. The overall shape when this is done is the same as in the first embodiment.

  Similarly to the above, from the third use position Q ′ and the first use position Q, it is possible to slide and rotate the second housing part 3 relative to the first housing part 2. However, in the present embodiment, the slide mechanism 50 causes the relative sliding rotation of the second casing 3 relative to the first casing 2 to rotate at the third usage position Q ′ and the first usage position Q. The direction is restricted to the other direction T2 side. For this reason, the fourth usage position U can be set from the third usage position Q ′ and the first usage position Q, but cannot be set to the second usage position R.

Next, details of the slide mechanism 50 will be described.
As shown in FIGS. 23 to 27, the slide mechanism 50 of this embodiment includes a first slit member 21, a second slit member 22, a first support shaft 51, a second support shaft 24, and a first support shaft 24. An engagement member 52, a second engagement member 26, a third engagement member 53, a first spring member 27, a second spring member 28, and a third spring member 54 are provided. The second support shaft 24 inserted into the second slit 32 of the first slit member 21 and the fourth slit 34 of the second slit member 22, the second slit 32 and the fourth slit 34, the second Since the configuration of the second engaging member 26 attached to the support shaft 24 is the same as that of the first embodiment, the description thereof is omitted. The configuration of the first slit member 21 and the second slit member 22 is basically the same as that of the first embodiment, but the configuration of the first slit 61 and the third slit 62 corresponding to each other is the first. It is different from the embodiment.

  That is, as shown in FIGS. 23 to 27, the first slit 61 and the third slit 62 are in a state where the first casing portion 2 and the second casing portion 3 are at the basic position P. The slit ends 61a and 62b communicate with each other. Furthermore, the first slit 61 and the third slit 62 are slit ends in the direction along the long sides 4a and 8a of the first casing part 2 and the second casing part 3, respectively, in the moving direction S. It extends toward the opposite side from 61a, 62b. In the present embodiment, the first slit 61 has a slide portion 63 and a widened portion 64. The slide part 63 is extended in a direction along the long side 4a of the first casing part 2 which is the movement direction S in the state of being at the basic position P. The widened portion 64 is formed in a substantially circular shape and wide at one slit end 61 a that communicates with the third slit 62 in a state where it is in the basic position P. The width B62 of the third slit 62 is set larger than the width B63 of the slide portion 63 of the first slit 61 due to the relationship with each configuration of the first support shaft 51 described below.

  As shown in FIGS. 28 and 29, the first support shaft 51 includes a support shaft main body member 70 and a support shaft auxiliary member 71. The spindle main body member 70 is inserted through the first slit 61 and the third slit 62. The support shaft auxiliary member 71 is attached to the support shaft main body member 70 and is inserted through the third slit 62. The spindle main body member 70 includes a first shaft portion 72 disposed in the first slit 61 and a second shaft portion 73 disposed in the third slit 62. As shown in FIG. 42A, the first shaft portion 72 is formed in a substantially rectangular plate shape as viewed from the front in the axial direction. In the state where the first shaft portion 72 is at the basic position P, the direction along the long side 72a of the first shaft portion 72 is the direction along the long side 4a of the first housing portion 2 which is the moving direction S from the basic position P. It is provided to match. Further, the short side 72 b of the first shaft portion 72 is formed in an arc shape so as to correspond to the circular shape of the widened portion 64 of the first slit 61. The diameter of the short side 72b, that is, the width B72a in the direction along the long side 72a is set substantially equal to the diameter D64 of the widened portion 64. For this reason, the first shaft portion 72 itself is configured to be rotatable around the axis within the widened portion 64 in the first slit member 21. On the other hand, the width B 72 b in the direction along the short side 72 b is set to be approximately equal to the width B 63 of the slide portion 63 of the first slit 61. For this reason, the first shaft portion 72 is restricted from rotating around the axis within the slide portion 63 and can only slide in the direction along the slide portion 63, and the first shaft portion 72 is a rotation that restricts mutual rotation with the first slit 61. It constitutes the regulation section.

  On the other hand, the widened portion 64 is provided with a stopper portion 65 that restricts the rotation of the first shaft portion 72. The stopper portion 65 is formed in a triangular shape with two sides 65a and 65b forming a right angle, protrudes inward from the widened portion 64, and is provided in a pair of point symmetry. In the state of the basic position P, the spindle main body member 70 can rotate relative to the first slit 61 in the one direction side T1 in the rotational direction, and each stopper portion 65 extends in the other direction side T2. Rotation is restricted by the contact of one side 65a. As described above, in this state, since the width B63 of the slide portion 63 and the width B72b in the direction along the short side 72b of the first shaft portion 72 are set to be approximately equal, the rotation of the spindle body member 70 is restricted. Thus, it is possible to move along the slide portion 63 while keeping the relative direction constant. When the spindle main body member 70 is rotated 90 degrees relative to the rotation direction other direction T2 from the basic position P, the first shaft portion 72 is moved to the stopper portion 65 as shown in FIG. 42C through the state shown in FIG. 42B. It contacts the other side 65b. As a result, the spindle body member 70 is restricted from further rotation at this rotational position. As will be described later, the state shown in FIG. 42C corresponds to the second use position R. When the first shaft portion 72 rotates within the widened portion 64, the direction of the short side 72b having the smallest width does not coincide with the width direction of the slide portion 63 that is substantially equal to the width B72b of the short side 72b. For this reason, the movement of the spindle main body member 70 toward the slide portion 63 along the movement direction S is restricted, and only rotation is allowed.

  As shown in FIGS. 28 and 29, the second shaft portion 73 of the spindle main body member 70 is coaxial with the first shaft portion 72, that is, centered on an axis passing through the rectangular centroid of the first shaft portion 72. It is substantially cylindrical and is provided so as to protrude from one surface of the first shaft portion 72. On the outer peripheral surface of the second shaft portion 73, a locking convex portion 73 a that protrudes in the radial direction, that is, the direction orthogonal to the axis is formed. In this embodiment, the locking projections 73a are provided as a pair so as to face each other in a direction that is approximately 45 degrees different from the direction along the long side 72a of the first shaft portion 72.

  In the spindle main body member 70, the other surface of the first shaft portion 72 opposite to the one surface from which the second shaft portion 73 protrudes and the end portion of the second shaft portion 73 are respectively provided with a first cover having a non-circular cross section. A fitting portion 70a and a second fitted portion 70b are formed. As will be described later, a first engaging member 52 and a third engaging member 53 are fitted into the first fitted portion 70a and the second fitted portion 70b, respectively. The support shaft main body member 70 is formed with a through hole 70c penetrating the first shaft portion 72, the second shaft portion 73, the first fitted portion 70a, and the second fitted portion 70b. Similarly to the first embodiment, the through hole 70c may be provided with a conductive wire that electrically connects the internal configuration of the first casing 2 and the internal configuration on the second casing 3 side. It is possible.

  As shown in FIGS. 30 and 31, the support shaft auxiliary member 71 includes a flange portion 74 and an insertion portion 75. The flange portion 74 has an outer diameter larger than the width B62 of the third slit 62. The insertion portion 75 is provided so as to protrude from the flange portion 74 and is inserted into the third slit 62. The support shaft auxiliary member 71 has the insertion portion 75 inserted into the third slit 62 from the side opposite to the side where the first slit member 21 is superimposed on the second slit member 22, and the flange portion 74 has the first portion. The second slit member 22 is locked. The insertion portion 75 has two outer peripheral surfaces having a radius of curvature corresponding to two planes in which the interval is set substantially equal to the width B62 of the third slit 62 and both slit ends 62a and 62b of the third slit 62. And a curved surface. As a result, the support shaft auxiliary member 71 can slide in the direction along the third slit 62 while sliding the two planes while restricting rotation within the third slit 62. . The support shaft auxiliary member 71 is formed with a fitting insertion hole 71 a that penetrates the flange portion 74 and the insertion portion 75 and into which the second shaft portion 73 of the support shaft main body member 70 is inserted. The diameter of the insertion hole 71 a is set substantially equal to the outer diameter of the second shaft portion 73. The second shaft portion 73 is inserted into the fitting insertion hole 71a so as to be rotatable around the axis inside the fitting insertion hole 71a. For this reason, the spindle main body member 70 and the spindle auxiliary member 71 can rotate relative to each other around the axis while being slidable along the first slit 61 or the third slit 62 together. It is possible.

  As shown in FIG. 49A, on the outer peripheral side of the fitting insertion hole 71a, a guide hole 71b that is communicated with the fitting insertion hole 71a and into which a locking projection 73a provided on the second shaft portion 73 is inserted so as to be able to advance and retreat. Is formed. The guide holes 71b are provided in pairs corresponding to the locking projections 73a. Each guide hole 71b is within a range of approximately 90 degrees in the circumferential direction along the outer periphery of the fitting insertion hole 71a. It is formed to contact and engage. For this reason, the support shaft auxiliary member 71 moves from the state in which it is in the basic position P with respect to the support shaft main body member 70 to the rotational direction other direction T2, and from the state shown in FIG. Until the portion 73a comes into contact with and engages with the other end portion 71d opposite to the one end portion 71c of the guide hole 71b, the portion 73a can rotate approximately 90 degrees. As will be described later, the state shown in FIG. 49C corresponds to the fourth use position U.

  As shown in FIGS. 23 to 27, the first engagement member 52 has a disk shape having an outer diameter larger than the fitting insertion hole 71 a and the guide hole 71 b of the support shaft auxiliary member 71. A through hole 52a corresponding to the outer shape of the first fitted portion 70a is formed at the center of the first engaging member 52. The first engaging member 52 is fitted into a first fitted portion 70 a that protrudes from the second shaft portion 73 of the spindle main body member 70 that is inserted into the third slit 62. The third engagement member 53 has a disk shape having an outer diameter larger than the width B 63 of the slide portion 63 of the first slit 61. A through hole 53 a corresponding to the outer shape of the second fitted portion 70 b is formed in the center portion of the third engaging member 53. The first engaging member 52 is fitted into a second fitted portion 70 b that protrudes from the first shaft portion 72 of the spindle main body member 70 that is inserted into the first slit 61. As described above, the first engaging member 52 and the second engaging member 53 are fitted into the first fitted portion 70a and the second fitted portion 70b of the spindle main body member 70, respectively. Therefore, the spindle main body member 70 and the spindle auxiliary member 71 are arranged in the first engagement member 52 and the third engagement member 53 in a state of being disposed in the first slit 61 and the third slit 62. It is sandwiched and connected together. Further, the spindle main body member 70 and the spindle auxiliary member 71 can slide and rotate as described above.

  The first spring member 27 and the second spring member 28 function as a holding portion that holds the positional relationship between the first slit member 21 and the second slit member 22. Further, the first spring member 27 and the second spring member 28 function as an auxiliary portion that assists the movement operation and the rotation operation when the first slit member 21 and the second slit member 22 are slid. To do. For example, a torsion coil spring is used as the first spring member 27. The first spring member 27 has one end 27 a fixed to the first slit member 21 and the other end 27 b fixed to the first support shaft 51. More specifically, the first end 27a of the first spring member 27 is wound around the first support convex portion 21b provided in the first slit member 21 as in the first embodiment, It is attached so as to be rotatable around the supporting convex portion 21b. The third engagement member 53 is fixed to the first support shaft 51. The third engaging member 53 is formed with a protruding portion 53b toward the first supporting convex portion 21b in a direction orthogonal to the direction along the first slit 61. A substantially cylindrical second supporting convex portion 53c is provided on the distal end side of the protruding portion 53b. The other end 27b of the first spring member 27 is wound around the second support convex portion 53c and attached rotatably around the second support convex portion 53c. The first spring member 27 is attached to the first support convex portion 21b and the second support convex portion 53c so as to narrow the distance between the one end 27a and the other end 27b. Thus, the first support convex portion 21b and the second support convex portion 53c are urged by the first spring member 27 so as to always increase the distance from each other. For this reason, as in the first embodiment, when the first support shaft 51 is located on the one slit end 61a side of the center position along the moving direction S of the first slit 61, It is urged along the first slit 61 toward the one slit end 61a side. On the other hand, when the 1st spindle 51 is located in the other slit end 61b side, it is urged | biased toward the other slit end 61b side.

  For example, a torsion coil spring is used as the second spring member 28. The second spring member 28 is fixed to a first engagement member 52 having one end 28 a fixed to the second slit member 22 and the other end 28 b fixed to the first support shaft 51. More specifically, one end 28a of the second spring member 28 is wound around a third support convex portion 22b provided on the second slit member 22 as in the first embodiment, so that the third support It is attached so as to be rotatable around the convex portion 22b. The support shaft auxiliary member 71 of the first support shaft 51 is formed with a protruding portion 71e in the direction orthogonal to the direction along the third slit 62 toward the third support convex portion 22b. A substantially columnar fourth support convex portion 71f is provided on the distal end side of the overhang portion 71e. The other end 28b of the second spring member 28 is wound around the fourth support convex portion 71f, and is fixed so as to be rotatable about the fourth support convex portion 71f. The second spring member 28 is attached to the third support convex portion 22b and the fourth support convex portion 71f so as to narrow the distance between the one end 28a and the other end 28b. Thus, the third support convex portion 22b and the fourth support convex portion 71f are always urged by the second spring member 28 so as to increase the distance from each other. For this reason, as in the first embodiment, when the first support shaft 51 is located closer to the one slit end 62b than the center position along the moving direction of the third slit 62, It is urged along the three slits 62 toward the one slit end 62b. On the other hand, when the first support shaft 51 is positioned on the other slit end 62a side on the opposite side, it is biased toward the other slit end 62a side. That is, the first support shaft 51 is urged by the second spring member 28 toward one of the slit ends 62 b and 62 a according to the position in the third slit 62.

  The third spring member 54 functions as a holding portion that holds the relative positional relationship between the spindle main body member 70 and the spindle auxiliary member 71 in the first spindle 51. Furthermore, the third spring member 54 functions as an auxiliary portion that assists the rotational operation when the support shaft auxiliary member 71 is rotated about the shaft relative to the support shaft 70. For example, a torsion coil spring is used as the third spring member 54. The third spring member 54 has one end 54 a fixed to the support shaft auxiliary member 71 and the other end 54 b fixed to the support shaft main body member 70. More specifically, in the first support shaft 51, another support portion 71 g is formed in the support shaft auxiliary member 71 along the third slit 62. A substantially columnar fifth support convex portion 71h is provided on the distal end side of the other overhang portion 71g. On the other hand, a protruding portion 52 b is also formed in the first engagement member 52 fixed to the first support shaft 51. A substantially cylindrical sixth supporting convex portion 52c is provided on the distal end side of the protruding portion 52b. The overhanging portion 52b of the first engaging member 52 is in a direction in which the angle formed with respect to the direction in which the other overhanging portion 71g of the spindle auxiliary member 71 projects in the state of the basic position P is approximately 45 degrees. It is overhanging. The spindle main body member 70 and the third engaging member 53 rotate relative to the spindle auxiliary member 71 within a range of approximately 90 degrees relative to the axis, which is defined by the above-described locking projection 73a and guide hole 71b. To do. By this rotation, the overhanging portion 52b of the first engagement member 52 is overlapped with the other overhanging portion 71g of the support shaft auxiliary member 71, and the other overhang of the support shaft auxiliary member 71 is placed on the opposite side. It is possible to project in the direction in which the angle formed with respect to the direction in which the portion 71g projects is approximately 45 degrees. One end 54a of the third spring member 54 is wound around the fifth support convex portion 71h and is fixed so as to be rotatable around the fifth support convex portion 71h. The other end 54b of the third spring member 54 is wound around the sixth support convex portion 52c, and is fixed so as to be rotatable around the sixth support convex portion 52c. The third spring member 54 is attached to the fifth support convex portion 71h and the sixth support convex portion 52c so as to narrow the distance between the one end 54a and the other end 54b. Thus, the fifth support convex portion 71h and the sixth support convex portion 52c are always urged by the third spring member 54 so as to increase the distance from each other. For this reason, in the first support shaft 51, the support shaft main body member 70 is rotated around the axis in either the rotation direction one direction T1 side or the other direction T2 side depending on the relative positional relationship around the shaft with the support shaft auxiliary member 71. It is energized towards the crab.

  Next, the operation of the portable terminal 40 and the slide mechanism 50 of this embodiment will be described with reference to FIGS. FIGS. 32 to 35, FIGS. 38 to 41, and FIGS. 44 to 47 show the configurations of the first casing unit 2, the second casing unit 3, and the slide mechanism 50 in each state. It is a schematic diagram showing a positional relationship, and only a minimum configuration is displayed for explanation. Since it is the same as that of the first embodiment from the basic position P to the first use position Q through the third use position Q ′, the description is omitted.

  FIGS. 32 and 33 and FIGS. 36A and 37A show a state where the first housing 2 and the second housing 3 are at the basic position P. FIGS. In this state, in the slide mechanism 50, as shown in FIG. 36A, the first support shaft 51 has a slide portion 63 extending in a direction in which the first support shaft 72 of the support shaft main body member 70 extends along the long side 72a. The first slit 61 is positioned in the widened portion 64 which becomes one slit end 61a while being coincident with the moving direction S which is the direction in which the first slit 61 is moved. Further, as shown in FIG. 37A, the second shaft portion 73 of the support shaft main body member 70 and the insertion portion 75 of the support shaft auxiliary member 71 are located at the other slit end 62 b of the third slit 62. The second support shaft 24 is positioned at one slit end 32 a of the second slit 32 of the first slit member 21 and the other slit end of the fourth slit 34 of the second slit member 22. 34b.

  First, a case will be described in which the operator gives an operating force to the first housing part 2 toward the one side in the moving direction S from the state where the basic position P is reached. Thus, as shown in FIG. 36B, in the first support shaft 51, the first shaft portion 72 of the support shaft main body member 70 moves in the moving direction S from the widened portion 64 of the first slit 61 to the slide portion 63. It becomes possible. As shown in FIG. 36C, the first shaft portion 72 can move until it abuts against the other slit end 61b of the first slit 61. 37B and 37C, in the first support shaft 51, the second shaft portion 73 of the support shaft main body member 70 and the insertion portion 75 of the support shaft auxiliary member 71 are the other of the third slits 62. It is possible to move from one slit end 62b to the other slit end 62a. Similarly, the second support shaft 24 can move in the movement direction S in the second slit 32 and the fourth slit 34. Thereby, similarly to 1st Embodiment, the 2nd housing | casing part 3 is along the moving direction S used as the direction along mutual long sides 4a and 8a with respect to the 1st housing | casing part 2. FIG. The first housing 2 and the second housing 3 can move, and the first use shown in FIGS. 34 and 35 and FIGS. 36C and 37C through the third use position Q ′. The position Q can be set. The functions of the first spring member 27 and the second spring member 28 are the same as those in the first embodiment from the basic position P through the third use position Q ′ to the first use position Q. Is omitted.

  In the first support shaft 51, the third spring member 54 always urges the support shaft auxiliary member 71 toward the rotation direction one direction T1 with respect to the support shaft main body member 70 (in other words, the support shaft support member 71). On the other hand, the spindle main body member 70 is urged toward the other side T2 in the rotation direction. For this reason, the support shaft auxiliary member 71 is slidably rotatable relative to the support shaft main body member 70 in the other direction T2 in the rotation direction. Is held and can be slid and moved together so as to become the third use position Q ′ and the first use position Q.

  From the state in which the first casing 2 and the second casing 3 shown in FIGS. 32 and 33 are at the basic position P, the operator moves to the second casing 3 in one direction T1 in the rotational direction. The second casing 3 is rotated on the first main surface 4 with respect to the first casing 2 by applying an operating force to the first casing 2. At this time, as shown in FIG. 43A, in the first support shaft 51, the insertion portion 75 of the support shaft auxiliary member 71 is restricted from rotating relative to the third slit 62 of the second slit member 22. ing. For this reason, as shown in FIG. 43B, the support shaft auxiliary member 71 rotates in the rotational direction one direction T1 together with the second slit member 22 fixed to the second casing 3. As shown in FIG. 43A, in the second shaft portion 73 of the support shaft main body member 70, the locking projection 73a is in contact with one end portion 71c of the guide hole 71b. For this reason, the support shaft main body member 70 is restricted from rotating with respect to the insertion direction 75 of the support shaft auxiliary member 71 in the rotation direction other direction T2. As a result, as shown in FIG. 43B, the spindle main body member 70 rotates together with the spindle auxiliary member 71 in the direction of rotation T1. Furthermore, as shown in FIG. 42A, the first shaft portion 72 of the support shaft main body member 70 is rotatable in the rotation direction one direction side T <b> 1 within the widened portion 64 of the first slit 61. For this reason, as shown in FIGS. 38 and 39, the second slit member 22, the spindle main body member 70 of the first spindle 51, and the spindle auxiliary member 71 are integrated to form the first spindle 51. The second support shaft 24 is slid and rotated with respect to the first housing portion 2 while sliding in the second slit 32 and the fourth slit 34.

  As shown in FIGS. 40 and 41, as in the first embodiment, when the second casing 3 rotates up to 90 degrees with respect to the first casing 2, The rotation 24 is regulated by contacting the other slit end 32 b of the second slit 32 and one slit end 34 a of the fourth slit 34. Furthermore, in the present embodiment, the first shaft portion 71 of the support shaft main body member 70 in the first support shaft 51 is in the widened portion 64 of the first slit 61 from the state shown in FIG. 42A to the state shown in FIG. 42C, the long side 72a of the first shaft portion 72 comes into contact with the other side 65b of the stopper portion 65 when rotated 90 degrees as shown in FIG. 42C, and the rotation is also restricted by the stopper portion 65. As described above, the second use in which the first casing portion 2 and the second casing portion 3 are substantially T-shaped in a state in which the first casing portion 2 is rotated 90 degrees from the basic position P. The position R can be set. Since the functions of the first spring member 27 and the second spring member 28 are the same as those in the first embodiment from the basic position P to the second use position R, description thereof will be omitted. Regarding the third spring member 54, between the basic position P and the second use position R, the relative positions of the first spindle 51 around the axis of the spindle body member 70 and the spindle auxiliary member 71. Is constant. For this reason, the third spring member 54 similarly functions as a holding portion so as to hold the relative positional relationship between the spindle main body member 70 and the spindle auxiliary member 71 around the axis.

  Next, from the state in which the first casing portion 2 and the second casing portion 3 shown in FIGS. 32 and 33 are at the basic position P, the operator moves to the second casing portion 3 in the rotational direction or the like. A case will be described in which an operating force is applied to the direction side T2 and the second casing 3 is rotated on the first main surface 4 with respect to the first casing 2. At this time, as shown in FIG. 49A (the same state as FIG. 43A), the insertion portion 75 of the support shaft auxiliary member 71 in the first support shaft 51 is connected to the third slit 62 of the second slit member 22. The relative rotation is restricted. As a result, as shown in FIG. 49B, the support shaft auxiliary member 71 rotates in the rotational direction other direction T <b> 2 together with the second slit member 22 fixed to the second housing portion 3. As shown in FIG. 49A, the second shaft portion 73 of the support shaft main body member 70 has a locking projection 73a disposed in the guide hole 71b. For this reason, the second shaft portion 73 is supported from the state in contact with the one end portion 71c of the guide hole 71b to the state in contact with the other end portion 71d as shown in FIG. 49C through the state shown in FIG. 49B. The shaft auxiliary member 71 rotates relative to the insertion portion 75 in the direction of rotation T1. Further, as shown in FIG. 48A (the same state as FIG. 42A), the first shaft portion 72 of the spindle main body member 70 slides in the first slit 61 in the direction along the slide portion 63 from the widened portion 64. It is movable. For this reason, as shown in FIGS. 44 and 45, the support shaft auxiliary member 71 is slidably moved in the third slit 62 on the first support shaft 51 around the second support shaft 24, and the support shaft The main body member 70 is rotated relative to the support shaft auxiliary member 72 around the axis, and the inside of the first slit 61 is slid while the relative position around the axis is fixed with respect to the first slit 61. While being moved, the second casing 3 slides and rotates with respect to the first casing 2.

As shown in FIGS. 46 and 47, as in the first embodiment, when the second casing 3 rotates up to 90 degrees with respect to the first casing 2, the first support shaft 51 is rotated. Rotation is restricted by the other slit end 61b of the first slit 61 and one slit end 62a of the third slit 34. Further, in the present embodiment, the support shaft auxiliary member 71 in the first support shaft 51 is 90 degrees with respect to the support shaft main body member 70 as shown in FIG. 48C from the state shown in FIG. Rotate relatively. In this state, the locking projection 73a of the spindle main body member 70 comes into contact with the other end 71d of the guide hole 71b of the spindle auxiliary member 71. For this reason, the rotation is also restricted by the locking projection 73a and the guide hole 71b.
As described above, in the state of being rotated 90 degrees with respect to the first casing portion 2 from the basic position P, the fourth use in which the first casing portion 2 and the second casing portion 3 are substantially T-shaped. The position U can be set. Since the functions of the first spring member 27 and the second spring member 28 are the same as those in the first embodiment from the basic position P to the fourth use position U, description thereof will be omitted.

  As for the third spring member 54, the support of the support shaft with respect to the support shaft main body member 70 is supported by the relative position of the support shaft main body member 70 and the support shaft support member 71 about the axis of the first support shaft 51. The direction in which the member 71 is urged around the axis changes. That is, in the state of the basic position P, as described above, as the holding portion, as the holding portion, the relative positional relationship around the axis between the spindle main body member 70 and the spindle auxiliary member 71 is held. Function. As described above, when the second casing 3 is slid and rotated with respect to the first casing 2 in the other direction T <b> 2 in the rotational direction, the first spindle 51 supports the spindle main body member 70. The member 71 rotates relatively around the axis. As a result, the relative positions of the fifth support convex portion 71h and the sixth support convex portion 52c that fix the third spring member 54 at both ends 54a and 54b also change. As shown in FIG. 44, when the second housing part 3 is further slid and rotated with respect to the first housing part 2 from the state where it is slid by 45 degrees, the fifth supporting convex part 71h and the sixth supporting part The relative positional relationship around the axis with the convex portion 52c for use is switched. As a result, the direction around the axis biased by the third spring member 54 is switched. For this reason, the urging force of the third spring member 54 acts so that the support shaft auxiliary member 71 rotates further about the shaft with respect to the support shaft main body member 70. Therefore, the third spring member 54 functions as an auxiliary portion for assisting the operation. In the fourth use position U, the urging force of the third spring member 54 presses the other end portion 71d of the guide hole 71b of the support shaft auxiliary member 71 and the locking convex portion 73a of the support shaft main body member 70 against each other. Act on. Therefore, the third spring member 54 functions as a holding portion for holding the state of the fourth use position U.

  Next, a case will be described in which an operating force is applied from the first use state Q and the second casing 3 is slid and rotated with respect to the first casing 2. First, in the state of the first use position Q as shown in FIG. 34 and FIG. 35, the second housing part 3 is slidably rotated in the rotational direction one direction side T1 with respect to the first housing part 2. Give operational force. At this time, as shown in FIG. 36C, in the first support shaft 51, the first shaft portion 72 of the support shaft main body member 70 is between the slide portion 63 of the first slit 61 of the first slit member 21. The rotation is restricted because it is arranged in the. In addition, as shown in FIG. 37C, the insertion portion 75 of the support shaft auxiliary member 71 is disposed between the third slit 62 of the second slit member 22, so that the rotation is restricted. Further, since the locking projection 73a and the one end 71c of the guide hole 71b are in contact with each other, the insertion portion 75 of the support shaft auxiliary member 71 rotates in the rotational direction with respect to the second shaft portion 73 of the support shaft main body member 70. The rotation to the one-direction side T1 is restricted. For this reason, the second slit member 22 fixed to the second casing 3 is the first slit member fixed to the first casing 2 around the first support shaft 51. 21 cannot rotate in the direction of rotation T1. Since the first support shaft 51 is locked to the other slit end 61b of the first slit 61 and one slit end 62a of the third slit 62, the first support shaft 51 is slid and moved. Further, it cannot be rotated around the second support shaft 24. As described above, in the state of being in the first use position Q, the second casing 3 is restricted from slidingly rotating in the rotational direction one direction T1 with respect to the first casing 2. .

  On the other hand, in the state of the first use position Q as shown in FIG. 34 and FIG. 35, the second casing 3 is slidably rotated to the other direction side T2 in the rotational direction with respect to the first casing 2. Give operational force. At this time, even if the first support shaft 51 is moved about the second support shaft 24 in the tangential direction of the other direction T2 in the rotational direction, the first support shaft 51 is the other end of the first slit 61. Is engaged by one slit end 62a of the third slit 62 and the movement is restricted. On the other hand, when the second support shaft 24 is moved about the first support shaft 51 in the tangential direction of the rotation direction other direction T 2, the second support shaft 24 is moved to the other side of the second slit 32. It is possible to move relatively from the slit end 32b toward one slit end 32a and from the one slit end 34a of the fourth slit 34 toward the other slit end 34a.

  In the first spindle 51, the rotation of the spindle main body member 70 is restricted by the first slit 61 of the first slit member 21 as shown in FIG. 36C. Further, the rotation of the support shaft auxiliary member 71 is restricted by the second slit 62 of the second slit member 22 as shown in FIG. 37C. On the other hand, the support shaft auxiliary member 71 rotates with respect to the support shaft main body member 70 from the state where the locking projection 73a is in contact with one end portion 71c of the guide hole 71b to the state where it is in contact with the other end portion 71d. It is possible to rotate by 90 degrees relative to the other direction side T2. For this reason, the spindle auxiliary member 71 of the second slit member 22 and the first spindle 51 rotates with respect to the spindle body member 70 of the first slit member 21 and the first spindle 51. The second casing 3 can be rotated with respect to the first casing 2 to the other side T2 in the rotational direction about the first support shaft 51. Thereby, it can be set as the 4th use position U as shown in FIG.46 and FIG.47. It is also possible to return from the fourth use position U to the first use position Q by performing the reverse operation to the above.

  As described above, according to the portable terminal 40 of the second embodiment, as shown in FIG. 22, the first casing 2 and the second casing 3 are the same as in the first embodiment. Can be set from the basic position P to the third use position Q ′, the first use position Q, the second use position R, and the fourth use position U. It is also possible to slide the first use position Q to the fourth use position U. On the other hand, sliding rotation to the opposite side to the second use position R is restricted by the locking projection 73a and the guide hole 71b. Accordingly, the second use position R is intended to be the fourth use position U by inadvertently rotating the second case part 3 with respect to the first case part 2 on the opposite side to the desired rotation direction. It is possible to prevent an erroneous operation such as As a result, it is possible to further improve usability as a whole by balancing convenience and erroneous operation. In the above description, the slide rotation from the first use position Q has been described, but the same applies to the slide rotation from the third use position Q ′. That is, while the slide rotation from the third use position Q ′ to the second use position R in the one direction T1 in the rotation direction is restricted, the fourth use position U is slid and rotated in the other direction T2 in the rotation direction. can do.

  In the present embodiment, the second use position R is restricted from the first use position Q and the third use position Q ′, while the fourth use position U can be set. However, it is not limited to this. While the fourth use position U is restricted by the relative positional relationship between the locking projection 73a and the guide hole 71b, the second use position R can be set.

  Further, the second support shaft may also have a two-member structure including a support shaft main body member and a support shaft auxiliary member, and may include a locking projection and a guide hole. By adopting such a configuration, in the state where the first use position Q and the third use position Q ′ are set, sliding rotation is restricted to both the one direction side T1 and the other direction side T2 in the rotation direction. . As a result, only sliding movement in the movement direction S is allowed, and the second usage position R and the fourth usage position U can be made only by sliding rotation from the basic position P.
